摘要： A method and apparatus for locating a memory leak in a program code by a computer device using a combination of dynamic analysis and static analysis approaches. The method includes dynamically analyzing the program to determine a memory leak characteristic; filtering out items which do not match the determined memory leak characteristic of the program to reduce a static analysis range to certain suspicious parts of a source code; and statically analyzing the suspicious parts of the program to locate the memory leak in the program. The apparatus includes a dynamic analyzer device to determine memory leak characteristics; and a static analyzer device to filter out items which do not match the determined memory leak characteristic to reduce a static analysis range to certain suspicious parts of a source code and locate the memory leak in the program.

摘要： A partition-based method for diagnosing memory leaks in Java systems, comprising dividing heap memory of a Java virtual machine into a plurality of partitions based on a partition plan, wherein each partition has at least one partition owner; monitoring the status of the respective partitions to determine whether there is a partition in which the memory space is exhausted; and if there is a partition in which the memory space is exhausted, determining that the memory leak may occur in the partition and analyzing the partition to obtain leaked objects and objects related to the leaked objects. The present invention also provides a partition-based apparatus for diagnosing memory leak in Java systems.

摘要： A blade head assembly for a hand-held hair cutting appliance includes a blade clamping device urging a cutting edge margin of a second blade in sliding engagement with a cutting edge margin of a first blade. The blade clamping device includes a clamping head operable for pivoting generally toward and generally away from the second blade about a pivot axis. The clamping head is resiliently biased generally toward the second cutting blade about the pivot axis into sliding engagement with the second blade. The second blade is slidable relative to the clamping head during reciprocating movement of the second blade relative to the first blade.
